The Shimano Dura-Ace FC-9000 11-Speed Crankset has once again revolutionized the market through common sense design that, for one reason or another, no one else has attempted. Finally, we can run either compact or standard rings on one spider, and even better, FC-9000 hasn't compromised a thing. In fact, it's lighter, just as stiff, and sleeker than 7900. Beauty and intelligence -- the total package.
